Kahului, Hawaii Pollen Count

Frequently asked

When is pollen worst in Kahului?

There's barely an off-switch for grass in Kahului — it pollinates year-round, so the usual "three waves" calendar flattens into a near-constant grass baseline. Tree pollen still spikes Jan–Apr and ragweed adds a Sep–Nov layer on top. Currently, grass pollen is what's driving counts this month.

What's in the air in Kahului right now?

Right now grass pollen leads in Kahului at a Very Low (1/5) level. The species actually in the air today: Grasses. On a quiet live day, Kahului's seasonal calendar fills in what's typically airborne this time of year.

Is tree or grass pollen higher in Kahului in spring?

In Kahului, the tree-versus-grass question is unusual: trees do peak Jan–Apr, but grass never really yields (year-round), so on most spring days BOTH are airborne. A spring bad day here is more often grass than tree, the reverse of colder regions.

What makes Kahului's pollen season distinctive?

Kahului sits in the warm tropical / sub-tropical zone, which means almost no off-season for grass, which pollinates year-round here, so the calendar is less about timing and more about the constant grass baseline. That shapes when symptoms hit and which allergen to watch.

How do I reduce pollen exposure in Kahului?

Through Kahului's peak windows (tree Jan–Apr, grass year-round, ragweed Sep–Nov), keep windows shut and run AC on recirculate; counts run highest on dry, warm, windy mornings, so push outdoor activity to late afternoon or just after rain, which clears pollen from the air. A HEPA purifier indoors, a saline rinse after being outside, showering before bed, and starting antihistamines a week or two before your worst local window all measurably cut symptoms.

What pollen index counts as high?

Pollen is reported on a categorical scale — None, Low, Moderate, High, and Very High. "High" and above means most allergy sufferers notice symptoms even with brief outdoor exposure, and sensitized people should limit time outside and pre-medicate. "Low" to "Moderate" usually only affects highly sensitive individuals.
